I am using SPI on my STM32F4 Discovery board together with libopencm3.
The function I use is spi_send located in spi_common_all.c
This function is blocking and sends one byte(short) at a time.
I wonder if there is some driver/API in libopencm3 to use SPI on STM32F4 in
interrupt or DMA mode?
Best regards
Johan
